DevFinanceTools is a collection of free, no-signup calculators for the money side of building software and freelancing. Everything runs in your browser — no account, no tracking beyond basic page-view analytics — and every tool shows its formulas and benchmarks so you can check the maths yourself.

Calculators

  • SaaS Metrics — MRR, ARR, ARPA, gross & net revenue churn, NRR, GRR, LTV, CAC, LTV:CAC, CAC payback and the Quick Ratio from one month of data, each with a benchmark.
  • Freelance Hourly Rate — works backwards from the take-home income you want, through unbillable time, expenses and tax, to the rate you need to charge.
  • Subscription Cost — list your recurring subscriptions and see the real total per month, per year and over five years. Saved in your browser only.
  • Uptime / SLA — turn an availability target like 99.9% into exact downtime per day, week, month and year, and back again.
  • Cost of Downtime — estimate what an outage costs in lost revenue, lost productivity and recovery, as a total and per minute.
  • Inflation — what a US dollar amount from one year is worth in another (CPI-U), with cumulative and average annual inflation.
  • Savings Goal — how much to save each month to hit a target by a date, or how long a fixed amount will take.
  • Hourly ↔ Salary — convert between an hourly rate and yearly, monthly and weekly pay, both directions.
  • Compound Interest — project a starting amount plus regular contributions, with a year-by-year breakdown.
  • LLM API Cost — estimate what an AI feature costs per request, day and month from token prices and volume, including prompt-caching savings.

There are also short plain-English guides on the topics behind the tools.

Possible disadvantages of JSONLint

    JSONLint does not offer an API for programmatic access, limiting its use in automated workflows and larger development pipelines.
  • Ads on the Website
    The website includes advertisements, which can be distracting for users and might affect the user experience.
